To celebrate Tamiya Korea's 30th anniversary, this lightweight 13mm all-aluminum bearing roller features a special design sticker featuring the red and blue colors of the Korean flag. It's a bold black color. Customize freely with three different stickers, or simply add a touch of class and charisma to your machine with the black aluminum roller itself. By drilling 10 holes, it's 30% lighter than the 13mm all-aluminum bearing roller in ITEM 15437. Equipped with a 520 bearing, it offers smooth rotation. Two bearing rollers, mounting screws, and aluminum spacers are also included.
